Big surprise - another shade tree asking for advice!
Daughter in Law's Grandfather - really good guy - fixed income...
Vent temperatures 80-90 degrees compressor engaged. Static equalized pressures 110 psi. What I notice most is the accumulator bottom half is cold but the two large lines at the top are not. High pressure line into condenser is damn hot.. Can't touch it so I'd guess around 160-180 degrees. This is a climate controlled vehicle as well..
Trying to help paw-paw out.. I've violated every rule by I do not know exactly what the charge is.. I'm broke as is he.. I've bought and installed several compressors, evap cores, etc. (purchased from AMA) vacuumed and charged to specs and all have been and are running for the last two years... Not an idiot but not diagnostically gifted either..
If this was presented to you, what would you do first? (and sending him to an AC specialist (hmm.. where will I find him here?)will be an option)..
Just looking for any flags or ahah's that go off in any of your collective minds.
Thanks for any advice....

The vent temperatures are about consistent with the high low side pressure.
Was the system recently worked on? With those low high side pressures, I suspect the OT isn't sealing properly and/or was damaged during installation. Air in the system is another possibility, but I would expect to see higher high side pressures.
I would recover the refrigerant, inspect and replace the OT, and assuming no debris on the OT, vacuum and recharge to spec.
